I never said anything about a "downstairs neighbor". That was Roger who did and my post was in context with his.

My goodness, how inattentive of me to assume that your direct reply to Roger actually was in context with what he was talking about, especially since you said "that is exactly how it works". I should have read your mind and realized that when you said explicitly that yours works exactly the same way, what you actually meant was that it works in a similar, but different, way. Which you didn't articulate.

So the Onkyo model is the HK525? I didn't know Onkyo made Harman Kardon receivers!

I can't say for every AVR manufacturer but that is exactly how it works on my Onkyo and my previous Harmon Kardon 525 from 2002.

The option was there to BM up to 200hz. If one were to BM a speaker that was 180-200hz, for example, that content would be sent to the left and right mains and if those were also BM'd then the rest would go to the SUB out.

Most AVR's only redirect the bass from other small speakers (plus LFE) to the R & L channels when the R & L main channels are set to large and the subwoofer is set to OFF.

If you set the R & L mains to small, then the bass management scheme is different. All redirected bass (plus LFE) is sent to the subwoofer in the all small speaker mode.

All AVRs have their peculiarities, so you have to test the AVR in question to figure bass management out. Are you sure about your bass management?

When the R & L mains are set to large (others small) in my AVR, the bass management sends redirected bass (and LFE) to the R & L mains. If the subwoofer output is activated, then total R & L bass is LP filtered and sent to the subwoofer output jack. That is the bass management mode that I use.

Atmos need to add a channel for sound from down below. They don't do that because people might say that Atmos sounds like hell!

Sound coming up from the floor a little breeze blows through the room a fog rolls along the floor with birds chirping in the trees and of course your couch needs to vibrate just in case there is an earthquake that maybe the future of atmos.

First post on AVS, I have been following the home theater Atmos thread with great interest. I am currently building a home with a dedicated home theater room and plan to implement a 7.3.4 setup with either on ceiling or possibly elevation/reflective speakers. I am trying to narrow down my choice of either Sonus Faber Venere , KEF R series or Martin Logan Motion series paired with REL subwoofers.
After much searching online for higher end speaker manufacturer's producing Dolby Atmos elevation speakers I managed to find an article on theregister.co.uk featuring KEF modules. The KEF speakers in the pictures below were recently used for a demo by Dolby in the UK, my original homeland. I am now settling into life in the wild west (Texas).
Not sure if this was taken from the same demo Keith recently attended?
Keith, Scott, Sanjay, Filmixer and many others have provided valuable information and insight into what I hope will prove to be a huge step up from TrueHD and DTS HD master audio, thank you to all who have posted.

Having heard the simulated reflected surround sound efforts of numerous soundbars, I was a little skeptical as to just how well the Dolby system would perform. It was with some trepidation then that I headed into Dolby’s London office for a demo of the home-bound Atmos kit, set to complement anything from a basic 5.1 set up to more lavish dedicated home cinema rooms. But not only does it work, it works bloody brilliantly.

I've been looking through all the documents I can find, but still not finding much concrete on the ceiling speaker locations.

I will have a 27' x 17' home theater (25' x 17' from screen wall to back wall) and 10' high ceiling. I'll be mounting speakers in the coffered beams.

I'm not sure if I should mount 4 or 6 speakers (I know the current receivers would be 7.1.4 and only 4 ceiling, but I have one shot to easily incorporate the ceiling speakers).

If two, where should I put the speakers. I have two rows of seating, with the back row being about 6' off the back wall. Has Dolby provided anything other than the crude drawings and stated one set in front of listening area and one behind?

My initial thinking is to put one set just behind the back row, maybe 5' off the back wall, which would be about 8.5' behind the front row (the only row occupied 95% of time) and then the front set 8.5' in front of front row. The downside to this is it puts one set almost on top of the back row and the other 16's in front.

I'm lost as to where to cut the holes in the coffers and run the wires to.

Any thoughts?

Dolby mentioned that more detailed installation white papers will be released around the time of the CEDIA Expo in September. Can you hold off a bit? I sure would.

And what Onkyo model allows this "two tier" bass management scheme? I've never even heard of this option (bass managing first to the L/R mains and then from there to the sub) before the current Atmos discussion.

Yes this was for the surrounds or center.

♦ Thank you for sharing, and welcome to AVS! ----------------------------------

I've noticed that on a few of these sites' latest Atmos demo reviews they keep bringing up that discs may be out towards the holidays. I'm assuming Dolby's "fall" release pronouncement has slipped a bit.

You would think that hardware and software would be ready to roll at the same time when something like this monumental shift in audio reproduction comes around. That would make for a great marketing coup, wouldn't it??

And how exactly are these studios going to announce Atmos releases on their own? They didn't exactly herald the debut of Dolby TrueHD and DTS Master Audio with a trumpet fanfare. Their home video marketing departments sometimes leave something to be desired.

I hope they're not expecting Best Buy and their "Blue Shirts" to do the legwork for them... that'll be a rip roaring success.

Just to be clear: the length of your room (front to back) is 27 feet? But your screen wall is 2 feet from the real front wall? How important is the back row? Is it for occasional overflow seating or used all the time? No. They're supposed to be issuing a white paper at CEDIA in a few weeks that addresses placement and installation of an Atmos set-up. Can you wait till mid September?

Yes, the shell of the room is 27' front to back, and the screen wall is actually about 30" in front of the front wall, but yes, essentially what you described.

95% of the time (or more) it will be just my wife and I in the front row, middle seats (two rows of four).

Yes, the shell is being built this week, but I think we can hold off until they come back to finish the theater (trim, acoustical treatment, etc.) in the fall. We just won't actually drill through the shell with wires until then.

Yes, the shell is being built this week, but I think we can hold off until they come back to finish the theater (trim, acoustical treatment, etc.) in the fall.

If you haven't built it yet, might I recommend you put the listeners' ears at 1/5th and 2/5th of room length from the back wall (65" and 130" from the back wall, respectively). Odd divisions of room length are where many of the problem frequencies (room modes) are roughly the same volume level, avoiding deep nulls (cancellations that cannot be fixed later with EQ).
